Answer:
Therefore, Sara’s current age (5 years later) is 19 years old.
Step-by-step explanation:
Let xx be Sara’s age five years ago. Therefore, Sara’s aunt’s age 5 years ago is 4x4x.
The difference in their ages is a constant, no matter how many years have gone by. (Can you see why?)
4x−x=42
3x=42
x=42/3
x=14
14+5=19
Therefore, Sara’s current age (5 years later) is 19 years old.
All you have to do is divide 48 by 3 and you should get exactly 16.
Answer:
Step-by-step explanation:
Only one answer will do for this question and that is 1.
y/x = 5/5 = 1
y/x = 6/6 = 1
y/x = 1/1 = 1
The one you have to be careful with is when x = 0 y = 0. You can't solve this by using y/x because 0/0 is undefined at this point.
Answer: <u>11.</u>
Step-by-step explanation: All you'd have to do in order to achieve this answer is by dividing 410 by 40 which gives you the answer of 10.25. In order to fit everyone they'll need a rounded number of buses; equalling 11.
